one of the many reasons america is so screwed up right now is because of our insistence on ignoring the very obvious statistically significant dimorphism between genders.

that doesn't' mean trans people and nonbinary dont' exist. We need to make accommodations for them where appropriate. However, it doesn't do any one any favors trying to homogenize how we teach kids. you inevitably help one at the expense of the others.

The fact that a small group of special interest groups have made "boys and girls are different" into some divisive political issue is absurd.

Maybe it's based on millions of years of biological differences in their capacities and functions (starting from body strength and role in reproduction), plus differences in social roles, of which some of the latter might be arbitrary, but some are necessary adjustments every historical society understood.

It doesn’t really matter. Most likely your indigenous population that was targeted to believe such terminal things like males and females being the same, will not be in power for long, let alone possibly even be around at all in the future. This modest puppy have is just a tiny little blip on the timeline where your society and culture was poisoned with a mental viruses to self-exterminate.

Your society will become an extinct group of people that probably will not even be remembered in another 200 years. If there is another advanced civilization yay attempts to understand the past like Europeans did, they will have an impossible time understanding what happened over the last 80 or so years when people lost the ability to tell the difference between males and females.

Have you ever heard the term “functional extinction”? It’s when a population still exists and it may even be reproducing, but the surrounding conditions and characteristics make it effectively inevitable that the population will go extinct over time. Being unable to differentiate between males and females and treating them the same is clear evidence of a terminal mental virus in humans. This very idea that males and females are the same will invariably die because it is not a successful reproductive strategy by definition.

Which country is that?

This sounds crazy, I know, but perhaps boys and girls are different.
